Hi Hal,
Thanks for the invite! I was actually browsing around this morning and thought maybe I'd like to give it a try. I'm actually working on a drawing for the August pen and ink challenge as well

.
Thanks for the compliments on both pieces!
I've noticed some perspective issues with the bridge also. The reflections are a little off and, like you said, the pilings on the bridge aren't correct. I would have also liked to add a little more variation of values to the trees in the background, but I was working with only the 24 set. The sky is also a little too busy

. I wish I could've taken some better pictures. The features are all very blurry, and the bridge is actually more defined in person. Many of the strokes along the top are pure yellows and oranges to show the light from the lamps. There are also a lot of reflected blues on the underside of the bridge to separate the it from the background, and to show the reflection of the water.
Glad you liked them, and thanks for the help!
